Am 5 weeks pregnant started having cramp in left back calf muscle no swelling no redness. Hip always hurts on left side and have a cyst on left ovary. Does it sound like dvt?

DVT and pregnancy. Your symptoms do not sound like DVT but there are 2 things that will help to solve the problem--a venous ultrasound of the leg veins which is very accurate for DVT or a d-dimer blood test which is significant for no clots if negative.
Possible. You have some symptoms and also a risk factor for DVT, it doesn't harm the baby or you to get an exam and and an ultrasound of your leg to make sure, as a DVT can be harmful to you and your baby.
